IMPROVEMENT IN METHODS OF WINDING. UNITING. AND G ROUPING BOBBINS.

Specification forming part of Letters Patent No. 186.045, dated January9, 1877 application filed April 20, 1876.

To all whom it may concern:

Be it known that I, ISRAEL L. G. RICE, of Cambridge, in the county ofMiddlesex and State of Massachusetts, have invented a new and usefulSystem of Arranging, and Winding, and Uniting the Yarn on Two or MoreBobbins, so as to form a single continuous thread, which invention isfully set forth in the following specification, reference being had tothe accompanying drawings.

The object of my invention is to make a continuous thread of the yarnthat is wound on several stunning-bobbins, so that the yarn on all thesebobbins may be drawn off' the tops of these bobbins without stoppage.This is done as follows: When an empty bobbin is placed on a spindle ofa spinning-frame it has a few turns of yarn wound upon it at the bottomof the bobbin by hand. This is to be done by the doffer. The object ofdoing this is to secure a sufficient length of yarn to tie onto-theouter end of the yarn on another bobbin; then the yarn is spun and woundonto the bobbin, as usual, care being taken that, in spinning, the yarnis not wound down at the very bottom of the bobbin, so as to cover overthe yarn that was wound on it by hand.

After the bobbin is dotted it is placed upon one of the pins a in thestand A, another full bobbin is taken from off the spinning-frame andplaced on a pin on the stand A, and the end of yarn that is on the topof one bobbin is wound around that bobbin one or two turns, so as tobring it at the bottom of the bobbin,

' and it is then tied to the end of yarn that is at the bottom of thebobbin beside it.

It will readily be seen that by drawing off the yarn from the top of onebobbin it will all unwind until it finally reaches the point where it isconnected with the yarn on the bobbin beside it. This is clearly shownin the elevation, Figure 1, the plan, Fig. 2, and the sectionalelevation, Fig. 3.

Fig. at shows a front elevation of a spinning-frame, with a shelf infront of the spindles, on which the stand A, with empty bobbins, may beplaced. In the operation of doffing, full bobbins may be taken from thespinningframe and put upon the stand A, while the empty bobbins on thestand may be placed on the spinning-frame. The doft'ers or the spinnerscan unite the ends of yarn on the bobbins when the frame is spinning.

Fig. 5 is a view of a bobb n with the end of the yarn that was first putupon the bobbin, (shown at b.) To keep it from being lost or snarled upit is slipped into a cut in the end of the bobbin.

The end of the yarn last put on the bobbin is shown at c. The knot wherec and b are connected is marked (1. The plan view, Fig. 2, fully showsthe system.

It will be found advantageous to so arrange thebobbins that theircenters will all point to a common center, and at their common center aguide shall be placed, through which the yarn is to be drawn. This isillustrated in Fig. 1.

In winding the bobbins they should be wound so that the yarn will lieupon them in a series of cone-shaped layers, as it does on the cops usedfor filling that are spun on the mule, this being the best mode forrapidly drawing it off the top.

I do not limit myself to any particular stand or order of arrangementfor these bobbins, the entire essence or principle of my invention beinguniting the yarn that has first been wound upon one bobbin to the yarnthat was last wound upon another at their respective ends, so that theyarn that is upon the bobbins may all be unwound without stopping,accomplishing, in fact, the same thing as if the yarn had all been spunand wound upon a single bobbin, with this difference, that the variousbobbins may, should it be desirable, have upon them different-coloredyarns-a thing which would be impracticable on a single bobbin, while themechanical difficulties of spinning a large amount of yarn on a singlebobbin are obvious to all familiar with the spinning-frame.

I claim as my invention- The method herein described of winding anduniting the yarn on two or more bobbins, and grouping these bobbins soas to form a single continuous thread, which may be drawn off withoutinterruption, whereby the process of spooling may be dispensed with.
